Tijiie locality. — Forest of Bouconne, Gers, France. 



Geographical distribution. — Lowlands of south-western France 

 from near base of Pyrenees to the Garonne. Limits of distribu- 

 tion not known. 



Diagnosis. — Like Pitymys pyrenaicus pyrenaiciis, but colour of 

 upper parts with a decided cast of buffy or pale wood-brown, 

 much as in P. savii. 



Measurements. — Type (adult female) : head and body, 93 ; 

 tail, 26 ; hind foot, 15 ; ear, 8. Average and extremes of five 

 adults from the type locality : head and body, 96 (93-104) ; tail, 

 25-6 (23-29); hind foot, 15-4 (15-16); ear, 7-7 (7-9). For 

 cranial measurements see Table, p. 775.

PITYMYS PLANICEPS Miller. 



1908. Pitymys planiccps Miller, Ann. and ]\Iag. Nat. Hist., 8th ser., i, 



p. 203, February, 1908. Type in Lataste Collection. 

 1910. Pitymys planiceps Trouessart, Faune Mamm. d'Europe, p. 190. 



Type locality. — Bareges, Hautes-Pyrenees, France. 



Geographical distribution. — Known only from the type 

 locality. 



Diagnosis. — Size about as in Pitymys subterraneus (condylo- 

 basal length of skull, 23 mm.) ; skull more flattened and depressed 

 than in any other known European member of the genus, the 

 dorsal profile nearly straight from posterior extremity of nasals 

 to back of interparietal ; teeth as in P. savii and P. pyrenaicus. 

 External characters not known. 



Skull and teeth. — In general outline as viewed from above 

 the skull resembles that of Pitymys savii in its rather short 

 rostrum, broadly spreading zygomatic arches and squarish brain- 

 case (length to back of interparietal equal to breadth over 

 zygomatic roots). Laterally and posteriorly it suggests P. stib- 

 terraneus, but with the normal characters of the species carried 

 to the extreme. The dorsal profile is essentially sti'aight from 

 posterior extremity of nasals to back of interparietal, though 

 there is a faint concavity in interorbital region and a slight 

 convexity at middle of brain-case. Interorbital region about as
